Abstract: This invention is a method for transfering energy alternately between two moving, rotating and swinging objects, and includes a pair of objects suspended in close proximity to one another in such manner that the suspension means for the two items may be wrapped around one another, and is characterized by one object swinging in a large circle with its suspension means wrapping about that of the other while the other stands relatively still, and subsequently the second object, without external interference, commences a circular and swinging action on its own, bringing the first to rest, and wherein the two objects may transmit motion from one to the other in this manner repetitively.
